1.An 800 kg car has an initial speed of 15 m/s measured at the bottom of a hill. Air resistance and other resistive forces cause a total of 10000 J of energy to be removed from the car as the car travels up the hill. The final speed of the car at the top of the hill is 5 m/s. What is the height of the hill
